Are parents of high caries risk Dutch children motivated to brush their children's teeth? An assessment using the health action process approach questionnaire.

PURPOSE: To assess the social cognitive constructs of the Health Action Process Approach (HAPA) of parents of high caries risk children to be treated under intravenous sedation (IVS) or with behavioural guidance techniques (BGT), and to assess the changes in these constructs for each treatment group after treatment. DESIGN: In this cohort study, 160 children aged 3-10 years were allocated by their paediatric dentist to either IVS (77.4%) or BGT. Their parents filled out a HAPA questionnaire, before (T1, n = 160), immediately (T2, n = 108) and three months (T3, n = 71) after their children's dental rehabilitation. RESULTS: Before treatment, all parents had high scores on all social cognitive constructs. There were no differences in mean HAPA scores between the treatment groups (p > 0.05). After treatment, mean scores changed in both groups. In the BGT group, action self-efficacy changed from 3.64 (T1) to 3.36(T2) (p = 0.027) and to 3.13 (T3) (p = 0.021) and coping self-efficacy changed from 3.63 (T1) to 3.23 (T2) (p = 0.015). In the IVS group, action planning changed from 3.25 (T1) to 3.05(T3) (p = 0.036) and action control changed from 2.58 (T1) to 2.82 (T2) (p = 0.012) and to 2.87 (T3) (p = 0.006). CONCLUSIONS: High scores on social cognitive constructs of parents of children referred to a paediatric dentist showed that they seem to be motivated to brush their children's teeth, irrespective of the treatment group. Small changes were observed in the HAPA constructs, however, these are not considered clinically relevant.

Guidelines on the use of fluoride for caries prevention in children: an updated EAPD policy document.

AIM: To update the exisitng European Academy of Paediatric Dentistry (EAPD) 2009 fluoride guidelines. METHODS: Experts met in Athens, Greece duirng November 2018 for the following groups: I Fluoride toothpastes, II Fluoride gels, rinses and varnishes, III Fluoridated milk, fluoridated salt, tablets/lozenges and drops, IV Water fluoridation. Systematic reviews and meta-analyses were reviewed and discussed for each of the groups. The GRADE system was used to assess the quality of evidence which was judged as HIGH, MODERATE, LOW or VERY LOW based on the assessment of eight criteria which can influence the confidence of the results. Following the quality assessment, GRADE was then used to indicate the strength of recommendation for each fluoride agent as STRONG or WEAK/CONDITIONAL. RESULTS: Parents must be strongly advised to apply an age-related amount of toothpaste and assist/supervise tooth brushing until at least 7 years of age. The EAPD strongly endorses the daily use of fluoride as a major part of any comprehensive programme for the prevention and control of dental caries in children. Regardless of the type of programme, community or individually based, the use of fluoride must be balanced between the estimation of caries-risk and the possible risks of adverse effects of the fluorides. Fluoride use is considered safe when the manufacturer's instructions are followed. Preventive programmes should be re-evaluated at regular intervals and adapted to a patient's or population's needs and risks. CONCLUSIONS: For the majority of European Countries, the EAPD recommends the appropriate use of fluoride toothpaste in conjunction with good oral hygiene to be the basic fluoride regimen.

Impact of apical extent of root canal filling on vertical root fracture: a case-control study.

AIM: To investigate the impact of apical extent of root filling on vertical root fracture (VRF) in a case-control study. METHODOLOGY: Eighty-six patients (119 roots) diagnosed with VRF in crowned root filled anterior and posterior teeth were selected. The cases were matched individually with control teeth in a ratio of 1:1 for age (±5 years), gender, tooth type, canal instrumentation method, master apical file (MAF) size and taper, technique of canal filling and time period after root filling. All root canals had been prepared using nickel-titanium (NiTi) rotary instruments and filled using the lateral compaction technique. The apical extent of root filling (overfilled to or beyond the radiographic apex or not overfilled and short of the radiographic apex) was recorded as the dependent variable by two individual examiners. Inter-examiner agreement was obtained using Kappa statistics. Recorded numbers of overfilled and not overfilled canals in cases and controls were analysed using chi-square tests and conditional logistic regression, and odds ratio was calculated. In addition, the frequency distribution of vertical and cross-sectional extensions and the course of VRFs were evaluated. RESULTS: The mean age of patients with VRFs was 50 ± 10 years with 27 (31%) males and 59 (69%) females. The Kappa score for inter-observer agreement was 0.832 (P < 0.001). There was a significant difference between cases and controls with respect to apical extent of root filling (P < 0.0001). When compared to roots not overfilled, overfilled roots had 11.5 times higher odds for occurrence of VRF (OR = 11.5; CI: 4.99 - 26.48). Most VRFs had a complete corono-apical longitudinal extension and were present bucco-lingually/palatally. CONCLUSION: After matching for age, gender, tooth type, MAF size and taper, canal filling technique and time period after root filling, root canals filled to or beyond the radiographic apex following lateral compaction had a greater association with VRF than canals filled short of the radiographic apex.

Will a chlorhexidine-fluoride mouthwash reduce plaque and gingivitis?

FOCUS QUESTION: What is the efficacy of a chlorhexidine (CHX) mouthwash (MW) containing sodium fluoride (NaF) compared to a CHX - MW alone on the parameters of plaque, gingivitis and discoloration? MATERIAL AND METHODS: MEDLINE-PubMed, Cochrane-CENTRAL, and EMBASE were searched for papers from inception to December 2017. The inclusion criteria were (randomized) controlled clinical trials conducted in human subjects with good general health and without removable prosthesis. Papers evaluating the effect of a MW containing CHX + NaF compared to a CHX alone were included. From the eligible studies, data were extracted, a descriptive analysis was performed and a meta-analysis when feasible. RESULTS: Independent screening of 412 unique papers resulted in 9 eligible publications presenting 10 clinical trials comparing the effect of CHX + NaF to CHX - MW and provided 13 comparisons. Five evaluated the MW as an adjunct to brushing and 8 were non-brushing comparisons of which 4 used an experimental gingivitis model. No significant difference was observed for plaque score reduction in the brushing studies the end scores (diffM; -0.04, P = .36; 95%CI: [-0.13, 0.05]) nor the differences (diffM; 0.11, P = .33; 95%CI: [-0.12, 0.24]). In the descriptive analysis, none of the experiments demonstrated a statistical significant difference regarding Gingival Index (GI), Bleeding Score and Discoloration Scores. For the GI, a meta-analysis of the difference of Means was not significant when included experimental gingivitis model studies end scores (0.01, P = .78; 95%CI: [-0.08, 0.11]) and the difference (0.01, P = .81; 9 5%CI: [-0.08, 0.10]) either for the end scores of brushing studies (diffM; -0.01, P = .82; 95%CI: [-0.10, 0.08]). CONCLUSION: From this study, it can be concluded that NaF and CHX may be present in the same MW without reducing CHX efficacy with respect to plaque and gingivitis scores. Moreover, no difference in the development of tooth discoloration was observed.

Whitening dentifrice and tooth surface discoloration-a systematic review and meta-analysis.

OBJECTIVE: The aim of this systematic review was to assess the effect of a whitening dentifrice (WDF) relative to a regular dentifrice (RDF) on the reduction of natural extrinsic tooth surface discoloration (ETD). MATERIALS AND METHODS: The MEDLINE-PubMed, Cochrane-CENTRAL and EBSCO-Dentistry and Oral Sciences databases were searched, up to April 2017. The inclusion criteria were as follows:(randomized)controlled clinical trials, healthy subjects ≥18 years of age, studies comparing WDF with RDF, a follow-up period of at least 6 weeks and studies scoring ETD as the stain area/extent, stain intensity or a composite score. Studies using an induced staining model were excluded. RESULTS: Independent screening of 851 unique papers resulted in 21 eligible publications, which included 32 comparisons. The descriptive analysis illustrated that the majority of comparisons showed a significant effect on ETD, in favour of WDF over RDF. The meta-analysis substantiated this observation and revealed that the difference of means (diffM) comparing WDF and RDF was a reduction for stain area of -0.44 [(95% CI: -0.55; -0.339) (P<.00001)] according to the original Lobene Stain Index; this result is in favour of the WDF. For the modified Lobene Stain Index, the diffM was -0.41 [(95% CI: -0.71; -0.10) (P=.009)]. For overall stain intensity, the diffM was -0.35 [(95% CI: -0.44; -0.25) (P<.00001)], and the composite score was -0.39 [(95% CI: -0.57; -0.21) (P<.0001)] and -0.54 [(95% CI: -0.66; -0.43) (P<.00001)]. Subgroup analysis differentiating between products that contained added chemical antidiscoloration agents showed a similar pattern. CONCLUSION: In this review, nearly all dentifrices that are specifically formulated for tooth whitening were shown to have a beneficial effect in reducing ETD, irrespective of whether or not a chemical discoloration agent was added.

A study of parental presence/absence technique for child dental behaviour management.

AIM: To examine the effectiveness of parental presence/absence (PPA) technique on the dental behaviour management of children. MATERIALS AND METHODS: This randomised control study recruited 61 child dental patients with uncooperative behaviour (Frankl 1 or 2) managed with AAPD-endorsed non-pharmacological techniques at a post-graduate university clinic. PPA was only used in the test group (31 children). Using a mini video-tape device, recording commenced at the onset of uncooperative behaviour and this was later rated, minute by minute, by a blinded experienced paediatric dentist. STATISTICAL ANALYSIS: Data were analysed with SPSS v.13.0. The Kolmogorov-Smirnov test was used for normality analysis. The Mann-Whitney U-test and Log Rank analysis were also performed. RESULTS: The mean point in time, after behavioural problems commenced that PPA or alternatives were applied was 1.82 ± 1.04 min. Behaviour improvement (technique success) was shown by 65.6% of all children. There was no statistically significant difference between the study and control groups in age, gender, mean Frankl score, in Frankl score 2 min before/after technique application or regarding the time point at which the technique was first applied. Behaviour improvement was seen in 17 patients (54.8%) in the PPA group and in 23 patients (76.7%) in the control group. CONCLUSION: PPA applied to various dental sessions as a behaviour management technique showed no advantage over other basic, non-pharmacological techniques.

Intrinsic tooth discoloration may occur as an adverse effect of fluoride and tetracyclines. Extrinsic tooth discoloration may occur as superficial staining or as discoloration of the superficial pellicle and/or biofilm due to chlorhexidine, liquid iron salts, essential oils, some antibiotics and stannous fluoride. Inhibition of orthodontic tooth movement has been reported due to the use of prostaglandin synthetase inhibitors. If medications or over-the-counter drugs induce hyposalivation or contain much sucrose, caries may develop. Erosion may occur if the acidity of medications or over-the-counter drugs is excessive. Attrition is a well-known adverse effect of serotonin reuptake inhibitors, antiparkinson agents, and antipsychotics. Congenital dysplasia is observed following childhood treatment with cytostatic drugs. External cervical root resorption is an adverse effect of internal teeth-whitening products. Prenatal exposure to antiepileptic drugs and childhood treatment with cytostatic drugs may cause dental agenesis. Antiseptic drugs applied for external teeth-whitening and toothpastes with additional ingredients to prevent extrinsic discoloration and creation of calculus, may cause tooth hypersensitivity.

[Preventive dentistry 8. Diet and caries]. / Serie: Preventieve tandheelkunde 8. Voeding en cariës.

The call to consume less sugar in order to improve the general health is becoming increasingly loud. The question is in what way consuming less sugar could also contribute to a lower risk of caries. This can be achieved by limiting the frequency of consuming sugary snacks. For oral health reasons, people in the Netherlands are advised not to consume things containing sugar more than four times between meals. Another way to make the diet less cariogenic is to substitute sugar in foods by non-caloric intense sweeteners, caloric sugar alcohols or 'new carbohydrates'. Non-caloric intense sweeteners and caloric sweeteners have been proven to be non-cariogenic. New carbohydrates still have to be individually tested.

Dental fear and caries in 6-12 year old children in Greece. Determination of dental fear cut-off points.

AIM: To present: the normative data on dental fear and caries status; the dental fear cut-off points of young children in the city of Thessaloniki, Greece. METHODS: Study Design: This is a cross-sectional study with two independent study groups. A first representative sample consisted of 1484 children from 15 primary public schools of Thessaloniki. A second sample consisted of 195 randomly selected age-matched children, all patients of the Postgraduate Paediatric Dental Clinic of Aristotle University of Thessaloniki. First sample: In order to select data on dental fear and caries, dental examination took place in the classroom with disposable mirrors and a penlight. All the children completed the Dental Subscale of the Children's Fear Survey Schedule (CFSS-DS). Second sample: In order to define the cut-off points of the CFSS-DS, dental treatment of the 195 children was performed at the University Clinic. Children⁁s dental fear was assessed using the CFSS-DS and their behaviour during dental treatment was observed by one calibrated examiner using the Venham scale. STATISTICS: Statistical analysis of the data was performed with IBM SPSS Statistics 20 at a statistical significance level of <0.05. RESULTS: First sample: The mean CFSS-DS score was 27.1±10.8. Age was significantly (p<0.05) related to dental fear. Mean differences between boys and girls were not significant. Caries was not correlated with dental fear. Second sample: CFSS-DS< 33 was defined as 'no dental fear', scores 33-37 as 'borderline' and scores > 37 as 'dental fear'. In the first sample, 84.6% of the children did not suffer from dental fear (CFSS-DS<33). CONCLUSION: Dental fear was correlated to age and not to caries and gender. The dental fear cut-off point for the CFSS-DS was estimated at 37 for 6-12 year old children (33-37 borderlines).

[The family's influence on the oral health of children. A peek behind the front door]. / De invloed van het gezin op de mondgezondheid van kinderen. Een kijkje achter de voordeur.

The prevention of dental caries seems fairly easy. The disease can largely be avoided by the daily removal of dental plaque using fluoride toothpaste and the control of sugary intakes. Most parents have sufficient knowledge and motivation to adhere to this prevention advice with respect to their children. Actual practice, however, proves quite difficult because parents experience barriers in implementing the advice. This article provides an overview of the most important family-related factors that influence children's oral health behaviour and dental caries experience. Factors include oral health-related attitudes of the parents, the way that parents deal with their children and communicate with them (parenting practices) and the organisation of daily life within the family (family functioning). It's important for oral health care providers to engage in conversations with parents to identify possible barriers. Tailored advice can then be given to help them improve their oral health behaviour.

[Preventive dentistry 4. Prevention and treatment of dentine hypersensitivity]. / Preventieve tandheelkunde 4. Preventie en behandeling van dentine-overgevoeligheid.

Many people sometimes experience pain when they inhale breath across the cingula or when they consume, for example, cold drinks. The most important method of prevention is to ensure that the dentine does not become exposed. If the dentine is exposed, both chemical and mechanical damage to the surface of the tooth must be prevented. Optimal treatment should be minimally invasive and primarily consist of advising the patient to brush his or her teeth and/or rub the sensitive area with a toothpaste especially developed to ease the pain of hypersensitive teeth. As an additional support a mouth rinse can be used. If this approach provides insufficient relief, professional measures can be deployed. Here, too, the least invasive treatment approaches ought to be treatment of first choice before moving on to more invasive therapies.

[Preventive dentistry 3. Prevalence, aetiology and diagnosis of dentine (hyper)sensitivity]. / Preventieve tandheelkunde 3. Prevalentie, etiologie en diagnostiek van dentine-over­gevoelig­heid.

Many people sometimes experience pain when they inhale breath across the cingula, or sensitivity and/or pain when they eat ice cream, for example. In some cases, however, this can become seriously unpleasant. In those cases, one can speak of dentine hypersensitivity. In Europe, an average of 27% of the population suffers from this. Dentine hypersensitivity is characterised by a short, sharp pain reaction after a warm or cold sensation. The external sensation causes an accelerated or converse flow of fluid in the dentinal tubules that excites the extremities of the nerve cells, which results in the sensation pain. For the external sensation, it is necessary that the cingula are exposed and the dentinal tubules are open. Dentine hypersensitivity is diagnosed after other possibilities have been eliminated.

Caries Incidence in a Healthy Young Adult Population in Relation to Diet.

In the past, epidemiological studies focused on cavitated stages of caries. The arrival of the International Caries Detection and Assessment System (ICDAS) in 2004 allowed for clinical measurements of the initial stages of enamel caries. However, since the introduction, most studies applying the ICDAS still have studied the diseased population. The objective of this cross-sectional observational study was to describe early enamel caries in a large healthy young adult population and determine the relationship with diet and oral hygiene measures. The study population consisted of 268 healthy participants without frank cavitation. The examinations were done visually and radiographically using ICDAS on all tooth surfaces. In total, 8.6% of the surfaces (occlusal > approximal > smooth) had caries, of which 92.0% were confined to enamel (28.5% ICDAS score 1, 54.0% score 2, 8.6% score 3). Thirteen percent of the occlusal and 63% of the approximal caries were found with radiography. Thus, radiography is quintessential for the diagnosis of approximal enamel lesions. We found a positive correlation between enamel caries (ICDAS 1 to 3) and the consumption of mono- and disaccharides and carbohydrates ( r = 0.226 and r = 0.188, respectively, both P < 0.01), as well as a negative correlation with alcohol consumption ( r = -0.202, P < 0.01). There was also a positive correlation between enamel caries and the energy intake from mono- and disaccharides (sugar kJ, r = 0.206, P < 0.01), which was independent of body mass index. Only 11 participants consumed less than 10% of total energy as sugar kJ, which is the recommended percentage of kJ from free sugar by the World Health Organization. No clear correlation was found with oral hygiene. In conclusion, in this healthy young adult population, caries was found in 97.8% of the subjects, mostly initial enamel caries (ICDAS 1 to 2) in the occlusal surface of molars, and was related with dietary factors.

[Preventive dentistry 1. Fluoride toothpaste, the cornerstone of caries prevention]. / Preventieve tandheelkunde 1. Fluoridetandpasta's, de hoeksteen van de cariëspreventie.

After the introduction of effective fluoride toothpastes in the 1970s oral health has improved significantly. Since that time, a lot of energy has gone into improving the toothpastes. An important improvement is the increased substantivity of fluoride and the increase in the duration of its effectiveness. In addition, attempts are currently being made to combine fluoride with effective re-mineralising systems, which is technically challenging. Due to a diversity of compositions, the effectiveness of toothpastes varies. It is, however, impossible to compare all available toothpastes on a 1 to 1 basis. The precise effectiveness cannot be deduced from the ingredients, nor is the dosage-response relationship between the concentration of fluoride and its effectiveness clear. The careful use of toothpaste will compensate for small differences in effectiveness. Times for tooth brushing should be chosen when there is enough time to brush carefully. After brushing, rinsing for one minute with the toothpaste slurry and a sip of water possibly increases the effectiveness of the toothpaste.

The effect of parental presence on the child's perception and co-operation during dental treatment.

AIM: This was to study the influence of parental presence during dental treatment on children's behaviour and perception. METHODS: Parents of 100 patients (mean age 7 ± 2.2 years) who visited the Postgraduate Paediatric Dental Clinic were randomly divided into two equal groups during one familiarisation and two treatment sessions: (1) parent present in the surgery/operatory and (2) parent absent (with their child observed through a window). Both an independent paediatric dentist and the parent rated the child's behaviour using the Venham scale. The child's perception was measured using the Wong-Baker Faces Rating Scale (FPRS) at the end of every session. Statistical analysis was performed with the IBM Statistics SPSS 22.0 (p < 0.05). Comparisons between variables were performed with the Mann-Whitney U, Wilcoxon and Friedman's tests. RESULTS: According to the paediatric dentist's rating, children's behaviour was worse when the parent was absent, with a significant difference only for the second restorative treatment session (p = 0.011). There was no difference on parents' rating child behaviour scores between the two groups. There was no difference of children's own perception between the two groups, except for any increased discomfort found at the second treatment (p = 0.021) when the parent was present. In both groups, the dentist rated lower Venham scores (better child behaviour), than parents did (presence: p = 0.001, absence: p = 0.038). Children recorded worse scores than both parents and the paediatric dentist. CONCLUSION: The only significant finding lay in the antithesis of how children perceived their last treatment session and how the dentist rated children's behaviour regarding parental presence. Parents' scores of their child's behaviour were unrelated to parental presence.

EAPD interim seminar and workshop in Brussels May 9 2015 : Non-invasive caries treatment.

AIM: This was to collect information for the 9th European Academy of Paediatric Dentistry Interim Seminar and Workshops to discuss the state of art on non-invasive caries therapy to be used if possible to formulate clinical guidelines by European experts in paediatric dentistry METHODS: Based on systematic reviews and additional papers were assessed for methods to prevent caries initiation and caries progression both in the state of pre-cavitation and cavitation without invasive technologies. RESULTS: The use of fluoridated water, careful diligent daily use of fluoride toothpaste, fluoride varnishes, pit and fissure sealants and leak-proof restorative materials without excavation of caries are evidence based for caries prevention and for non-invasive treatment of pre-cavitated and cavitated caries. Other technologies are far less evidenced based and would not logically fit in guidelines for the non-invasive treatment of caries. Recent studies on cavitated lesions in the primary dentition demonstrate that thorough oral hygiene practices may arrest progression. This strategy depends heavily on the strategies in the dental surgery to change behaviour of children. An important aspect is for advice to be tailored at recall intervals to ensure compliance and to timely detect unnecessary and unwanted progression of the lesions. CONCLUSION: Non-invasive therapies have been proven to be effective for caries prevention and the management of pre-cavitated caries lesions. Non-invasive therapies can also be effective to arrest cavitated lesions but the success depends greatly on behavioural changes of patients to brush the lesions.

Best clinical practice guidance for management of early caries lesions in children and young adults: an EAPD policy document.

BACKGROUND: The European Academy of Paediatric Dentistry (EAPD) encourages prevention and arrest of active dental caries. Therefore, the present guidance provides evidence- and clinically-based recommendations for detecting and diagnosing early/non-cavitated caries lesions, risk assessment and disease management. METHODS: A search of different databases was conducted using all terms related to the subject. Relevant papers were identified after a review of their titles, abstracts or full texts. Three workshops were held during the corresponding EAPD interim seminar in Brussels in 2015. Several statements were agreed upon and, furthermore, gaps in our knowledge were identified. RESULTS: Following the systematic reviews and outcomes of the seminars, it was concluded that visual and radiographic caries detection should be utilised as a basic diagnostic approach to locate, assess and monitor non-cavitated caries lesions in primary and permanent teeth. As another important evaluation step, a caries risk assessment should be performed at a child's first dental visit, and reassessments should be performed on a regular basis. It is widely accepted that non-cavitated caries lesions can be managed non-invasively in the majority of cases. The spectrum of measures includes a low cariogenicity tooth-friendly diet, daily and appropriate management of the biofilm, home and within the dental office/surgery usage of fluorides as well as sealing techniques. CONCLUSION: The detection and management of non-cavitated caries is an essential aspect of preventive dentistry. Therefore, the EAPD encourages oral health care providers and caregivers to implement preventive practices that can arrest early caries and improve individual and public dental health.

Declining Caries Trends: Are We Satisfied?

WHO data suggest that all over the world the prevalence of caries has declined at the end of the previous and in the first decade of the present century. This decline started wherever the use of effective fluoride toothpaste became commonplace. Even though the decline is considerable with a 90 % reduction in DMFT for 12-year-olds in Western Europe and the USA, caries still affects 60-90 % of the children throughout the world. In the high- and middle-income countries, the nature of caries has changed from a rapid progressing disease of childhood to a slowly progressing disease throughout adulthood and even old age. However, throughout the world, the circumstances for caries differ, e.g., low-income countries experience more caries with higher sugar consumption, while between high-income countries this correlation is reversed. In high-income countries, fluoride is widely used and preventive programs in dental offices are in place. These programs, if effective, may not be a realistic option in low-income countries. In order to reduce caries in the world even further, the use of effective and affordable fluoride toothpaste should be encouraged and enabled.

[Evidence-based clinical practice guidelines in oral care 2: process and content of evidence-based guideline development]. / Evidencebased klinische praktijkrichtlijnen in de mondzorg 2. Proces en inhoud van evidencebased richtlijnontwikkeling.

In 2014, an advisory report was published by a national working committee concerning how the current, applied method of evidence-based guideline development in healthcare can be used in oral care in a national guideline programme. In an independent Institute of Knowledge Translation in Oral Care, as yet to be established, primary and secondary oral care providers will participate in the programme in order to improve the quality of oral care in the Netherlands. With the launching of the Institute of Knowledge Translation in Oral Care, clinical guideline development will have the benefit of a structural approach, in which 3 successive steps can be distinguished: preparation, development and authorisation. In each of these steps, oral care providers and associations will be actively involved. In this way the aim is to give as much consideration as possible to the needs of those in the field of oral care in the choice of topics for guideline development and to secure the specific character of oral care in the actual establishment of guidelines for clinical practice.
